Patented Sept. 16, 1913.

Application flled' July 17, 1912. Serial No. 709,963.

To all whom it may concern Be it known that we, Isaac W. Knn'rz and JOSEPH W. RANKIN, citizens of the United States of America, residin at Peru, in the county of Miami and State 0% Indiana, have invented certain new and useful Improvements in Vaginal Syringes, of which the following is a specification, reference being had therein to the accompanying drawing. 4

This invention relates to syringes and more especially to vaginal syringes provided with means for dilating the vagina.

The principal object of the invention is to provide an Improved form of dilater attachment for a vaginal syrin With the above and other 0 jects in view, as will be hereinafter apparent, the invention consists in general in certain details of construction and combinations of parts described and claimed in the annexed specification.

In the drawings, Figure 1 is a side elevation of the syringe with the dilater collapsed. Fig. 2 is a section showing the dilater expanded. Fig. 3 is a vertical section of the protecting cap of the device. Fig. 4 is a; detail view of the movable ring and connecting end of the springs. Fig. 5 is a vertical section of a nut employed. Fig.

6 is a. section onthe line 6-6 in Fig. 1.

The invention resides principally in the discharge tube or nozzle of the syringe and consists of a body 10 ofan elongate pear shape and having a threaded boss 11 at its upper end and being provided with a threaded shank or stem 12. In cross section the body is star-shape? as shown in Fig. 6. Slidable on the dy is a ring 13 to which are attached the lower ends of a series of thin steel springs '14. The other ends of these springs are attached to the 11p per end of the body 10 adjacent the boss 11 and on this boss is screwed a protecting cap 15 which. covers the ends of the springs and prevents injury when inserting the syringe. On the threaded stem 12 is screwed a knurled nut 16 having the enlarged end 17 to provide a recess 18 adapted to receive the ring 13.

In operation the device is entered in the position shown in Fig. 1 and when in osition, the knurled nut is rotated. T is causes the springs to bow outwardly and dilates the va 'na.

What is c aimed is In a device of the character described, a hollow body, a sleeve adjustable lengthwise on said body and having its upper portion enlarged and spaced from said body, a ring loose in said space, a threaded projection on the inner end of said body, radial outwardly curved projections extending along the upper part of said body and having cross apertures therein connecting with the bore of said body, normally straight outwardly curvable sprin having their inner ends secured on sai projections and their outer ends secured to said ring in the annular space of said sleeve, and a cap threaded on t e projection at the inner end of said body, as specified.

In testimony whereof we hereunto afix our signatures in presence of-two'witnesses.
